Different kinds of computers are designed for different purposes. The computer at the heart of your laptop is optimized for different puprposes than the one in your phone or the one in your mouse. The simplest computers are those that are designed to take inout from the phyiscal world and control output devices in the […]
I made a little automatic slipper foot massager with the Lilypad Arduino and some of the Lilypad Vibe Boards for the actual massager. The sensor it uses is a Lilypad Accelerometer that I’m only using as a basic tilt sensor. Essentially it detects when the slipper is in a more vertical position (like when you

This Instructable details how to build a holiday dreidel display for your roof. It uses coat hanger wire, rope light, and an Arduino controller to control a fading demo mode and a “spin” mode. In the demo mode, the symbols fade in and out, going from one to another. In “spin” mode, the symbols flash

This is my second version of my arduino robot after “Build your first robot”. My Second version is slightly complicated as compared to my first one but offers better features. In this instructable I’m going to show you how to build a fast robot which can measure temperature, find things in front of it, stream

The breathalyzer microphone is a system for the inconscpicuous collection of blood-alcohol content level data sets. In other words, you can measure a person’s sobriety with a device, that for all intents and purposes, looks no different than a standard microphone. This tool adds new dimensions of truthiness to any standard interview. It can also
Introduction We designed a device that measures and graphs various aspects of AC power and acts as a computer-controlled remote switch. With the recent push for green energy and environmental friendliness, more and more people are concerned about their personal daily power usage. We developed a microcontroller-based device to measure AC power. The user will
This instructable will show you how to build a portable Touch Screen Oscilloscope for less than 40 U$! The oscilloscope is one of the most powerful electronic instruments that is available to electronics hobbyist, experimenters, and engineers. It is mainly used to measue time-varying signals. Any time you have a signal that varies with time(
The idea behind this post is to bring together some robot designs and trasform them in a new device with new hardware and standard software (arduino of course) and so easier to use. These robots have three things in common: a mechanical structure, the hardware and the software. While the mechanical part is necessarily different,
The photo depicts a speed controller, wired on a breadboard which allows you to vary the resistance in the potentiometer in order to, in effect, control the speed of the small DC motor. The big picture problem is creating an efficient PWM motor controller that allows for an analog variance of voltage across the motor.
